This invention relates to a molding apparatus capable of being used for molding frozen dainties.

An object of the invention is to mold ice lcream in a convenient form for dispensing to the consumer.

Another object is to provide molded frozen dainties having a center or layer of fruit, nuts or other edible iilling.

The accompanying drawings illustrate the invention: y y

Figure 1 is a plan View of an apparatus embodying the invention, the upper section being partially broken away and molded articles being shown in some `of the cups of the lower section.

Fig. 2 is an elevation partly in section on the line indicated by 2-2, Figure l, the plungers of the upper section being in position to eject the upper molded sections of the molded articles from the cups of the upper section.

Fig. 3 is an elevation from the line indi-v cated by 3 3, Fig. 2, the shafts being `in section. v y n Fig. 1 is a plan view of the perforate inember employed for forming a layer or center of fruit, nuts or other filling upon the upper faces of the lower sections ofthe molded articles.

Fig. 5 is a sectional detail of one ofthe cups of the lower section and its plunger, a fragment of the perforate member being shown in position for applying a filling to the upperface of the section of ice cream in the cup. y

Fig. 6 is a view of one of the frozen dainties molded in the apparatus.

There are provided two identically` constructed mold sections 11, 12. For conven1- ence in describing the operation of the apparatus, the section 11V will be termed the upper section and the section 12 the lower section. The sections 11, 12 are held in spaced relation by posts 13 screw-threaded intothe upper face of thelower section near the corners thereof and detachably seated in sockets 111 in the lower face of the upper section 11. vIt is not absolutely necessary to so space the sections, but it is preferred to do so. The sections 11, 12, are provided with concavities or cups 15, each concavity being approximately heinispherical.f Communicating withthe cups 15 are spring chambers 16 containing coil springsV 39 which surround plungeis17 thatfextend through the springA chambers and that are adapted tov be pro- Jected'by the springs intothe cups.` The vplungers `17 are enlarged to form heads18 and, when the plungers are retracted, `the heads 18 iit in the spring chambers. The

outer faces `of the heads 18 are concave so as to constitute a continuation of the -walls of the cups, when the heads are retracted within the spring chambers.` l

The stems of the plungers 17 pass through holes 19 in the sections and project from said sections through anoperating member 21 and are connected by nuts 20 to said operating member. `The operating member 21, in the instance shown, comprises a plate provided near its corners withv guides 22'which work in ways 23 in the sections.

The plates 21 are provided at their opposite ends with bearings 24: for shafts 25, there being a shaft for each section. The shafts extend lengthwise of the sections near the lmiddle thereof and project beyond the ends of the sections. Each shaft is provided with a cam`26 secured, in this instance, to the shaftby fitting on a seat 27 of angular cross section. Each of the shafts 25 provided at its opposite ends with operating knobs 28 which are secured to theshaft by nuts 29. The knobs'28'ia're held against turning rela` `tive to the shafts by reason of the knobs fit- The` ting angular seats 30V on Ithe shafts. cams 26 are preferably toothed, as shown,

`and they engage followers in the form "of spur pinions 31 rotatably mounted on studs 82 which are screw-threaded into the ends of the sectionsll, 12. e

From the foregoing it will be readily un-k derstood that, to retract the plungersagainst the pressure of theQ springs 39, it is only necessary for `the operator to rotate the knobs 28 so as to cause the largerfradii portions 33 of the cams to engage the pinions 31 so as to force the plates 21 away from the sections 11, 12,.` The cams 26 arepieferably provided at their peripheries with shoulders4 Figure; is shown a member operating member, toothed followers mounted on the sections, and toothed cams on the shafts engaging the followers.

ers of each section, a shaft rotatably mounted 10 on each operating member, and cam means operated by the shafts to move the operating members against the pressure of the springs to retract the plungers.
